One of those three or all of those three are not tightly sealed thus you're breathing in air. Your hookah can smoke like a champion even with that small bowl but I think you're having a sealing issue.
The rig does sit into a grommet, but the problem i have with the grommet is that when i put the rig into the base with the grommet after a while it gets loose. for this reason i tried the robinsons bottle that was a perfect fit for the rig (Without the grommet).
With regards to the grommet for the bowl, the rig is soldered with the ash plate along with a "metal" grommet at the top (replacing a rubber grommet). the reason why im using foil under the bowl is to give it a tight fit ontop of the soldered grommet as it it loose without the foil.
I dont have a grommet on the hose, i never knew i needed one? where would this be fitted as my mates i don think has a grommet there.
